FOOT-ACTUA'I'ED FUEL-CONTROL ATTACHMENT FOR MOTOR-CARS.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application flled March 29, 1815. Serial No. 17,818.

To all whom it may concern:

Be it known that I, GEORGE W. HUMMEL, a citizen of the United States, residin at Beggs, in the county of Okmulgee and tate of Oklahoma, have invented certain new and useful Improvements in Foot -'Actuated Fuel-Control Attachments for Motor-Cars, of which the following is a specification.

This invention relates to motor cars of that type equipped with hand operated mechanism for controlling the throttle valve on the carbureter, and my object is to produce a simple, strong, durable and cheap attachment whereby the throttle valve can be operated by foot power and closed by a spring, the use of such attachment being desirable as it leaves the driver of the car free to retain control of the steering wheel with one hand and operate the brake with the other in the event an emergency stop is necessary. I

With the object named in view, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and ointed out in the appended claim and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1, is a perspective view of a part of a Ford car equipped with foot attachments for controlling the supply of gas to the en c. Fig. 2, is a vertical section taken throug the dash of the car and showing my attachment in side elevation.

In the said drawing, 1 indicates the sides of the frame or chassis, 2 the engine or motor, 3 the dash, and 4 the floor of the car adjacent the dash, the floor being omitted from Fig. 1. a y

5 is the stationary support for the steering column 6. The steering wheel is omitted together with its usual equipment for crating the shaft 7 whereby power is transmitted through the crank arm 8 and a link mechanism 9 to the operating arm of the usual butterfly valve 10 or its equivalent for controllin the supply of combustible mixture from tfie carbureter 11 to the on no.

In the Ford car the connection between the arm 8 and the arm of the butterfly valve 10 is a (plain rod; To accomplish my object, this re in eflect has a section cut out of it, and interposed and pivoted to the adjacent ends of the remaining ortions is a link 12 which link is preferab y in the form of a ring, as shdwn, fulcrumed at 13 on one section of the link rod and pivotally connected at 14 to the other section of said rod. I also provide means for operating the link 12 to effect opening or closing of the butterfly valve Without afiecting the position of the shaft 7 and without interfering with the operation of said shaft to open or close the butterfly valve. The means referred to consists of a spring to hold the link 12 in the position shown by full lines Fig. 1, which represents the closed position of the butter fly valve, and a foot actuated rod for disposing the connected parts in the position indicated by dotted lines same figure, whereby to open the butterfly valve and supply gas to the engine. The spring is identified by the reference character 15 and the rod by the reference character 16. As shown the rod extends slidingly throu h the dash and floor 4 a is pivotally hoofied to an arm 17 of the ink ring 12 and the spring 15 is attached at its opposite ends to the pivoted end of said rod and to the dash, this rin when unopposed holding the parts with t e gas cut oif from the engine. Ordinarily in driving the car, the operator will advance rod 16 by resting one oot against its rear end and when he desires to cut off the supply of gas he removes his foot and permits the spring 15 to close the butterfly valve. The rod 16 will have sufficient play in the dash to be capable of swinging laterally when the butterfly valve is operated through rotation of the shaft 7 so as not to interfere with the bodily endwise movement of the link connection constituted by the sections of rod 9 and the link ring 12 connecting said sections.

From the above description it will be aparent that I have produced a foot actuated el-control attachment for motor cars em bodying the features of advantage enumerated as desirable and I wish it to be understood that while I have illustrated and described what'I now deem the preferred embodiment of the same, I reserve the ri ht to make all changes fallin within the spirit and scope of the appende claim.

claim:

The combination in a'motol: car, of an engine, a carburetor, a valve for controlling the passage of combustible gas from the carbureter to the en no, a crank arm for said valve, a rock sha a crank arm therefor to operate in a vertical plane, a short rod pivoted at one end to the crank arm, a rod aline'd'with the first named rod and spaced therefrom and pivotally connected at one end to the crank arm of the valve :1, floating lever fulcrumed for movement 1n a horizontal plane on the first named rod and pivotally connected to the adjacent end of the other rod, a slide rod pivoted at its front end to said floating lever, and a retractile spring attached at its front end to the front end of said slide rod and at its rear end to a fixed part of the car.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
